The French Revolution was a failure,
One of the most obvious failures of the French Revolution was the Reign of Terror from 1793-94. The Terror, which was orchestrated by Robespierre and his followers, was ostensibly a way to provide for the security of the Republic by exposing traitors to the people. In reality, it was used by Robespierre as a means to consolidate and strengthen his hold on power. Instead of putting into practice the democratic ideals of liberty and equality that he spoke of in public, Robespierre used the Terror to execute or imprison thousands of people who he viewed as a threat. The Terror came to an end only after Robespierre himself was sent to the guillotine.
Another failure in the revolution,
The French Revolution also failed to establish a constitutional monarchy or a representative government. France began in 1789 with the absolute monarch of Louis XVI and ended with the military dictatorship of Napoleon Bonaparte. In between there were various elected legislative bodies, but these groups became more radical and dogmatic as the Revolution progressed. The leaders of these Assemblies cared for the people only to the extent that they could help them hold on to power. Men such as Robespierre, and later the members of the Directory, used the National Assembly for their own personal gain.
his people considered him a hero because he stopped all the bloodshed from the revolution and prevented a return of the Bourbon monarchy.
Once he had his domestic power base in order, he turned to France's borders, which were under attack by reactionary foreign powers, who wanted to restore Bourbon sovereignty to France and prevent the revolutionary ideals from spreading to their lands. He quickly defeated Frances enemies and over the next decade he put France in a constant state of war. As well as enlarging the French empire, Napoleon made changes to the countries which shared a border with it. Napoleon was a strong and powerful military commander, he fought many of his enemies and it took seven coalitions to defeat him. His reasoning for war was to spread his ideas of the French Revolution. As he continued to enter battles winning land he would then make a family member the king. Napoleon himself because King of Italy, his brother Louis became King of Holland and his brother Josepha became king of Naples. With Napoleon only allowing direct family to have control of a country it appears as though he is trying to gain as much power as he possibly can to for a strong alliance among the other countries.
Some good things that came out of the French Revolution,
The French revolution destroyed the social discriminative class system in France and declared equality for all. The revolution came up with the equality and career open to talents, i.e., appointment and promotion was to based on talents and ability. This led to rise of middle class who had acquired education to positions of responsibilities.
The revolution gave birth to the revolutionary ideas of liberty, equality and fraternity. These ideas started in France and got spread to other areas like Italy, German, etc. such ideas promoted equality, freedom and democracy and good governance. This made France to be a nursery bed of democracy in Europe.
